I am trying to sort a List<List<Integer>>.
The internal list will have 3 values. (X-coordinate, Y-coordinate, Start/end)
Now while it works for most of the cases, the sorting fails for a specific case.

The logic behind it is:
If x value is not equal we sort them on the basis of x.
if equal then:
if both start then on basis of height in descending order.
if both end then on basis of height in ascending order.
else whichever was the start.

( checkNumber initialized before if as int checkNumber=1; 1 - because we update before any user action ( program starts and empty texfields are being filled with data) and only after that it will be updating with if ( when any button is pressed)
So the question is how to get all 15 questions ( get 15 index) and avoid ArrayIndexOutOfBoundsException: length=15; index=15
Thanks in advance!

I have custom C++ classes which I want to run on my android app. I am successfully binded my C++ files using CMakeLists. But as my classes uses opencv, I am getting an issue which is obvious

fatal error: 'opencv2/core.hpp' file not found

Then I tried to add opencv library on my android app, downloaded the open cv android sdk and tired to add it on my project following this guideline. However I dont want to include java classes related to opencv as my Java code doesnt require opencv jni classes.

I just want to import opencv on my c++ file. I tried to copy the .so files on my libs folder and tried to compile. But none of them work. I think I have to build the opencv library on my project using ndk but I dont know how.

I am using phonegap-plugin-push on Cordova and some app users get push notifications every ~30 seconds. The problem is when their device is OFFLINE and they go online say 1 hour later, they are suddenly flooded with 120 push messages at once, crashing and freezing the app.

I have a webapp using Faye for push notifications. I've packaged that web app inside a cordova android app and runs fine, and I'm using Faye.js client to listen for notifications.

The problem is that, when the application is not running in the background, notificatons are not being listened.

I've used intents in the past (a very long time ago) for an Android native app to listen for notifications but I don't know which is the "Cordova" way to do this. I would also like this to be compatible with iOS.
